RESERVE-GASOLINE TANK.

Application. filed April 2'7,

To all iii/mm it may concern:

Be it known that l, Janus A. SKAGGS, a citizen of the United States,residing at Canton, in the county oi? Stark and State of ()him haveinvented certain new and useful IllllJPOVQllltlIltS in Reserve-GasolineTanks, of which the following is a specification.

This invention relates to auxiliary fuel anks and is especially adaptedfor use upon motor vehicles. The improvement has for its objects toprovide a reserve fuel tank which may be easily connected to the usualvacuum feed system such as is commonly used upon auton'iol'iiles, andwhich will be automatically filled by the operation oi? the vacuuu'iteed tank, the reserve supply o'lt' gasoline being trapped in thereserve tank which may be called upon when the main supply carried bythe vehicle is exhausted.

The above and other objects may be attained by constructing the devicein the manner illustrated in the accompanying drawing, in which- Figure1 is a top plan view of a reserve tank embodving the invention, showingthe action of the same to the vacuum teed system; and

Fig. 2, a vertical, sectional view through the reserve tank showing thevacuum feed mechanism .in elevation.

Similar numerals refer to similar parts throughout the drawing.

The instrument board of an automobile is indicated at 1 and the vacuumtank 2. such as is con'unonly used in vacuum teed systems, may beconnected thereto in the usual manner. Suction is created in the tank 2by connecting the same to the intake manifold 3 in the usual manner asby the pipe 4:.

The tube at is connected to the upper end of the vacuum tank 2 and atube 5 is also connected to the upper end of the vacuum tank and leadsto the main tuel supph tank trom which the fuel is drawn by suction inthe usual manner, to the vacuum teed tank. A pipe (5 connected to thelower end of the vacuum teed tank and leads to the carburetor for thepurpose of feeding; the fuel thereto by gravity as is customary in thesesystems.

The reserve tank 7 may be supported by the curved brackets 8 connectedto the in strument board as by the flanges 9, a bolt 1923. Serial No.635,026.

it) drawing the brackets together between the tanks 2 and T and a bolt11 connecting the flanged ends 12 ot the brackets and clan'ip-inp; thereserve tank 7 thercbetween.

A l" 13 is provided in the pipe 5 between the main fuel supply tank andthe tank 2 and connects with the upper end of the reserve tank '7. Thelower end of the reserve tank may be provided with a drain aperture 14normally closed by means of the screw plug 15.

A tube It; is extended through the central aperture 17 in the upper endot the reserve tank and has a flange 18 connected to its lower end, saidflange being soldered or otherwise connected to the lower wall oi thereserw tank. The threaded nipple 1!) in the lower wall of the reservetank registers with the tube 16 and receives the L. 20 to which isconnected the pipe 21, a T 22 being provided in the pipe 6, intermediatethe vacuum tank and the carburetor for connecting the pipe 21.

One or more apertures 23 are provided in the tube 16 at av point spacedfrom the bottom of the reserve tank and a screen 2% surrounds the lowerend portion of said tube, being connected thereto at a point above saidapertures.

it rod or tube as shown at 25 is slidably mounted in the tube to andnormally rests upon the upper end of the L 20 and as the same titssnugly within the tube 16, the apertures 23 are thus normally closed.

A. wire 26 is connected to the upper end of the tube and leads throughthe tube 27 to the instrument board, being provided with an operatingknob 28 upon its extremity and with a shoulder 29 near its outer end forengagement with the bracket 30.

J-l spiral spring 31 is located around the lower portion of the wire 26and interposed between the washers 32 and 33. which are held inengagement with the tubes 25 and 27 respectively, by means of thespring".

lhe tube is thus normally held in the position shown in. Fig", 2 of thedrawing. closing the apertures 23 and prevel'iting fuel from passingfrom the reserve tank through the pipe into the pipe 6 which leads tothe carburetor.

it will be obvious that as gasoline is sucked from the mam fuel supplytank to the vacuum tank 2, a portion of the gasoline will be receivedthrough the T 13 into the reserve tank and since the connection of thesame to the pipe 6 is normally closed, the reserve tank will continue toreceive gasoline in this manner until the same is filled after which allof the gasoline sucked through the pipe 5 will pass into the vacuumtank.

Should the car run out of gasoline while on the road, the reserve supplyin the tank 7 may be conveyed by gravity through the pipe 21 into thepipe 6 to the carburetor by ulling the wire 26 outward until the lowerend of the tube 25 is raised above the apertures 23 in the tube 16,permitting the gasoline in the reserve tank to pass through saidapertures into the tube 16 and thence to the carburetor as abovedescribed.

I claim 1.111 combination with a fuel supply and a carburetor, a vacuumtanlg a continuous suction pipe connecting the fuel supply with thevacuum tank, a feed line connecting the vacuum tank with the carburetor,a reserve tank, a T in the top of the reserve tank communicating withthe suction pipe and an outlet in the reserve tank communicating withthe feed line.

2. In combination with a fuel supply and a carburetor a vacuum tank, acontinuous suction pipe connecting the fuel supply with the vacuum tank,a feed line connecting" the vacuum tank with the carburetor, a reservetank, a T in the top of the reserve tank communicating with the suctionpipe and an outlet in the reserve tank communicating an outlet in thereserve tank eommunicating with the feed line. means tor normallyclosing the outlet, and means tor manually opening the outlet.

4-. ln combination with a fuel supply and a carburetor, a vacuum tank, acontinuous suction pipe connecting the fuel supply with the vacuum tank.a fed line connecting the vacuum tank with the carburetor, a reservetank a T in the top of the reserve tank communicating with the suctionpipe and an outlet in the reserve tank eommuuieating with the teed linea tube extending entirely through the reserve tank and connecting withthe outlet and havingan openinp spaced from the bottom of the tanktorming a sediment trap. a tube slidablv mounted through the lirst namedtube. spring means for normally holding the second named tube in loweredposition to cover said opening and a flexible wire connected to thesecond named tube for raising the same above said opening.

In testimony that I claim the above. T

have hereunto subscribed my name.
